Actually now all the civil ATCO's are Military. Zapatero is a magician, didn't you know?
Jokes aside, they just been royal decreed over form the ministry of development to the ministry of defense...and...et voila! Magic! Now they really have no rights, and military law is their law. And as we all sort of know: in the military you just do as your boss says; or else.
Forget just culture, forget doing what you think is best. From a couple of hours ago there are Mil Commanders and Military-ish Police (guardia civil) in every control centre (and tower? I guess at least in the big ones) and you better do as you're told.
This is gonna end in tears.
